I love 'pussy'! All the others just sound weird... '****' is nice as well. And 'cock' is powerful too but I like the original: 'penis'!!!
I love 'Vulva' for the external lady bits. It's the proper scientific/medical term and its such a beautiful word, so rich and expressive. When I'm aroused i like to use the old word '****' which is so sexy. I also love the word 'Cleft' which is powerful, sexy and factual. think ladies parts are so incredible and gorgeous and the words used should respect that. For the inner parts, 'Vagina' is fine. a pretty word and, again, the correct term. Why invent names for your parts when the real words are so gorgeous? The same applies to Breasts and Nipples though i do like Boobies as well. When it comes to our parts I think Testicles and Scrotum are just fine, certainly better than Balls and Penis is again scientifically correct and more pleasant than cock etc.
Punane and foo foo for the vagina has to be my Go go words and for my go go for the penis would have to be vertical joy ride or lollipop and of course magic stick
